LATCH FOR DOORS 0F MOTOR VEHICLES.

Application filed; January To allwlwm it may concern:

Be tknown that I, ETIENNE BENoi'r DES- .coM Es, a citizen of the FrenchRepublic, re-

siding at Paris, in' the Republic of France, have invented new anduseful Improvements in Latches for Doors of Motor Vehicles, of which thefollowing is a specification.

The present invention has for its object a latch for the doors of motorvehicles which is so constructed that all play of the vehicle door withrespect to the vehicle body is etii ciently and permanently preventedeven after a long use, whereby all noise and vibrations resulting fromsuch play are also done away with.

In the accompanying drawing givenby way of example: 7

. Fig. 1 is a front elevation (inside of the vehicle) of a latchaccording to the invention.

Fig. 2 is a cross-section thereof on'the line A-A (Fig. 1).

Fig. 3 i a longitudinal section of the same on the line B-B (Fig. 1).

Fig. 4 is a erspective view of the lock casing as seen rom the front(inside of the vehicle). I

Fig. 5 is a corresponding perspective view of the door catch.

As shown in the drawing, the latch comprises two main pieces: the lockcasing 1 mounted on the door, and the door catch 11 secured to theupright of the door frame. The lock contains a locking mechanism whichmay be of any suitable type and comprises, as shown, a guide plate 3 anda lock bolt 4: operated either from. the inside by a lever 5 providedwith the usual handle'or from the outside by means of a small lever 6provided with an ordinary outer handle. Said levers respectively actupon two projections 7 and 8 on the lock bolt 4; which always tends tobe returned into the closing position by the spring 10.

The door catch 11 has a projecting portion 2 in the shape of a hook ornose which has a pyramidal or like form, for instance, a conical form,and has formed therein a conical aperture 12. The nose 2 fits when thedoor is closed within an aperture 13 formed in the lock casing 1 andhaving a corresponding shape.

The bolt 4 has a conical end 9 which en- 8, 1922. Serial No. 526,486.

gages with the inner wall of the conical ap' erture 12 in the nose 2,under the action of the spring 10, sothat the nose 2 is always forcedtightly into the aperture 13. In this manner, all play is obviated andtherefore all noise is prevented in spite of the vibrations of thechassis when travelling.

The conical end 9 of the lock bolt is cut at the end on an oblique plane17 and the end of the nose 2 is also bevelled at 2 in order tofacilitate when the door is closed, the easy engagement of the nose 2into the aperture 13 and also the withdrawal of the lock bolt 4.

It is obvious that the invention is not limited to the constructionaldispositions above described.

'Having now described my said invention, I declare that what I claim anddesire to secure by Letters Patent is:

1. A latch for vehicle doors comprising in combination a lock casing, adoor catch, one of said members being provided with a pyramidal recess,a yramidal projecting part on the other mem r and engaging into saidrecess when closing the do0r, a lock bolt having a rectilinear movementin the lock casing in a direction at right angles to the movement of thesaid projecting part and a spring acting on said lock bolt, the doorcatch having an inclined face with which the lock bolt is adapted toengage, so as to force the said projecting part into the said recess. 2.A latch for vehicle doors comprisin in combination a lock casingprovided with a pyramidal recess, a door catch, a pyramidal projectingpart or nose on said door catch adapted to engage into I the saidpyramidal recess in the lock casing and having formed therein a conicalhole, a lock bolt provided with a conical end and having a rectilinearmovement in the lock casing in a direction at right angles to themovement of the said nose and a spring acting on said lock bolt, thesaid conical end of the lock .bolt being adapted to engage with theinner wall of said conical hole in the projecting nose so as to forcethe said nose into its recess in the lock casing.

In testimony whereof I have signed my name to this specification.
